Today on their blog, Facebook announced a new gaming feature their messaging app. Called Instant Games, the new feature is set to release 30 countries with 17 launch titles, including Word With Friends Frenzy, Space Invaders, Galaga, Pac-Man, and more.

We’ve made it very simple to start playing: In the latest version of the app, open a conversation with a friend (or friends!), tap on the game controller icon just below where you type your message, and choose a game to start playing right away. After you finish a round, people in the conversation will see your score and will have the opportunity to challenge you back. People can also discover games within the Messenger search field, or on Facebook News Feed where they can play solo or challenge friends back in Messenger.

They also write that “1 billion people use messenger every month,” so you can expect for Earth’s collective productivity to drop by a seventh.

Instant Games is available today. Check out Facebook’s blog for more info.
